While gaming, your CPU and GPU work together to create a smooth, enjoyable experience.
Low CPU usage while system bottlenecks, improper cooling, or outdated software can cause gaming. Ensure proper cooling, update drivers, and check for dust buildup. Resetting BIOS and optimizing settings may also help improve performance.
In this article, we’ll dive into the common reasons behind low CPU usage during gaming, explain what’s considered normal, and share tips to boost your system’s performance.
What Is CPU Usage in Gaming?
CPU usage in gaming shows how much work your computer’s processor, the CPU, is doing while you play.
The CPU handles tasks like controlling game characters, processing physics, and managing game rules. It’s similar to GPU usage, which deals with graphics and visuals.
Low CPU usage often means your GPU is doing most of the work, which is typical for many games. A balanced CPU and GPU usage can lead to smoother gaming experiences.
How CPUs and GPUs Work Together
CPUs and GPUs work as a team during gaming. The CPU handles general tasks like game logic, character movements, and game settings.
Meanwhile, the GPU focuses on graphics—rendering images, textures, and visual effects. The CPU sets up instructions, and the GPU takes over the heavy graphics work, creating the game’s visuals.
When both are in sync, games run smoothly. If the CPU is slow, the GPU might wait, causing lag. Balanced performance helps achieve the best gaming experience.
Common Reasons for Low CPU Usage in Games
1. Graphics-Heavy Games
Games focused on stunning visuals often rely more on the GPU. The CPU works less hard in these cases, leading to lower CPU usage since the GPU handles most graphics-related processing.
2. Proper Optimization of the Game
Well-optimized games balance CPU and GPU tasks effectively. This reduces strain on the CPU, leading to lower usage. Proper optimization ensures smoother performance, ensuring the CPU isn’t overloaded during gameplay.

3. Bottlenecks Caused by Other Hardware
Low CPU usage can also result from hardware bottlenecks, like a slow hard drive or underperforming GPU. If another part of your system holds things back, the CPU won’t reach total capacity, causing lower usage.
Tips to Increase CPU Usage in Games
- Close Background Applications: Shut down unnecessary apps running in the background to free up CPU resources for gaming.
- Update Drivers: Keep your CPU and GPU drivers updated to ensure they work efficiently with your games.
- Adjust Game Settings: Lower graphics settings to shift more workload to the CPU if underutilized.
- Overclock Your CPU: Safely overclocking can boost your CPU’s performance, making it handle more tasks during gaming.
- Enable High-Performance Mode: Switch to your system’s high-performance power mode to prioritize CPU power over energy-saving.
- Upgrade Cooling System: Better cooling helps maintain optimal CPU temperatures, allowing for more consistent and efficient performance.
High GPU Usage vs. Low CPU Usage: Is It Normal?
Yes, seeing high GPU and low CPU usage in gaming is often customary. This usually means the game is graphics-intensive, making the GPU handle most of the workload, like visuals and rendering.
The CPU still handles game logic, but it’s not pushed to its limit. There’s no need to worry if gameplay is smooth without any lag. However, if you experience stuttering, you might need to check if your CPU is holding back performance.
Signs That Low CPU Usage Is a Problem
Low CPU usage can be problematic if your game needs to catch up or stutter. This could mean the CPU needs to be fully utilized, possibly due to bottlenecks in other hardware.
If the game isn’t running smoothly, even with low CPU usage, it’s worth checking your system for potential issues, like slow storage or a weak GPU.
How Game Optimization Affects CPU Usage
1. Well-Optimized Games
Well-optimized games make the most of your system’s resources, including the CPU. They efficiently distribute tasks so the CPU isn’t overworked or underused. This results in smooth, stable gameplay without unnecessary lag or stuttering, providing a better gaming experience.
2. Impact of Bad Optimization on CPU
Bad optimization can cause the CPU to either struggle or not be fully used. It may lead to performance issues like high CPU load, poor frame rates, or stuttering. This often happens when a game must properly balance tasks between the CPU and GPU.
Hardware Bottlenecks and CPU Usage
1. How RAM and Storage Affect CPU Performance
RAM and storage play critical roles in CPU performance. If your system doesn’t have enough RAM, the CPU may struggle with tasks, causing lag. Slow storage can also delay data processing, making the CPU wait, which can lower performance.
2. Impact of Cooling Solutions on CPU Usage
Reasonable cooling solutions help maintain stable CPU temperatures, preventing it from overheating. When the CPU stays cool, it can perform better without throttling. Poor cooling leads to higher temperatures, reducing CPU performance and causing it to underperform during intense gaming.
What Happens If a Game Is CPU-Bound?
When a game is CPU-bound, the CPU is the limiting performance factor. The game relies heavily on the processor for tasks like physics, AI, and game logic. If the CPU is not fast enough, it can cause lag, stuttering, or frame drops.

Can Software Cause Low CPU Usage?
Specific software or background tasks can cause low CPU usage by not demanding much processing power. Programs that are not resource-intensive or well-optimized might only partially engage the CPU. Antivirus scans or power-saving modes can also limit CPU usage, affecting overall performance.
Should You Be Concerned About Low CPU Usage?
Low CPU usage is usually acceptable, especially if the game runs smoothly. It may indicate that the GPU is handling most of the work. However, if you notice lag, stuttering, or poor performance, your system might be worth investigating for potential issues.
Extremely Low CPU Usage While Gaming
If your CPU usage is shallow during gaming, it could be that the game is not demanding much from your CPU, or the GPU is handling most of the workload. As long as performance is smooth, it’s usually not a concern.
Why my CPU usage is low like mostly under 10%
CPU usage under 10% may mean the game isn’t demanding much from your processor. It could also suggest that other hardware, like the GPU, does most of the work, leaving the CPU with less to do.
Low CPU usage when gaming Windows 11
Low CPU usage in Windows 11 while gaming is expected if the game is more GPU-intensive. The OS might also manage resources efficiently, limiting CPU usage to keep power consumption down. It’s normal as long as the game performs well.
Sudden drop in CPU usage while gaming
A sudden drop in CPU usage while gaming could indicate a bottleneck in another component, like the GPU or RAM. It could also be due to background tasks taking priority, or the game may need to utilize all the CPU’s potential.
Low CPU util on CPU-intensive games.
If CPU utilization is low on CPU-intensive games, there may be issues like CPU bottlenecks, power-saving settings, or poor game optimization. The CPU isn’t fully used in such cases, potentially affecting game performance and frame rates.
Low CPU Utilization While Playing Games
Low CPU utilization during gaming means the game might be more GPU-dependent or the CPU handles tasks easily. It’s generally acceptable if the game runs smoothly, but if there’s lag, other system issues might be causing the low usage.
